I can relate to the question where to start. I guess it all starts with where are you know and where do you want to go and why! For myself i played 20 years ago all cords and runs on an acustic. learned from familly and basic cord books as long as i played with a group all was good. As like many people life got in the way and i just stopped however always kept my guitar. Now i have time so I still have the interest and started to look at clips on utube and followed best icould. Then i said to myself there is abetter way. I like acustic and have a twelve string Yamaha and have had it for a long time because it sounds full while you play be yourself songs like Me and Bobby Megee. I found gitaur tricks and with its basic instruction i started all over again from the start to bring back some of my skills and build on new ones. then as i got a little better at scales and leads i started to select songs i liked. Songs that you like are somtimes hard to find on sites. With an open mind i looked at other sites and finally selected three sites one for electrice classic rock, one for blue grass picking and one for over all selection. At this point it seems to be working ( however perfect practice is the most important tool) In a short time working slow (important) and staying with it even if you think your skills and mind will never get it. You will get better every day. Now i have three guitars that are all diffrent and all great to play all the songs i like. I have my original twelve string, Gibson Les Paul for classic rock and a martin DCAP-1 six string for overall and picking. Have a goal be honest with yourself and practice and enjoy the process. You will be amazed.
